For all you GTers that are into cosmetics and science (or only one!) there is a cool interview with cosmetic Chemist Kevin Ewell on xoVain. He talks about some cool stuff like parabens, sulfates, drugs vs. cosmetics, marketing, why some product with the same ingredients can have wildly varying price points.
Kevin is a Research and Development cosmetic chemist who's been involved in making products for companies such as Johnson & Johnson, Dove, Murad, Fresh, Benefit, and Bath & Body Works. He cut his teeth as a toxicology scientist doing safety testing on cosmetics and their raw materials before jumping into formulating for cosmetic companies.
It's written by one the less annoying people on xoVain, so bonus points!
